Serial No. 604.548.

Be it known that I, ROBERT A. CARTER, Jr., a citizen of the United States, and a resident of New York city, in the county of Queens and State of. New York,'have invented certain new and useful Improveas breeze, is mixed with an ments in Volatilizer Apparatus, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to volatilizers for driving off the volatile matter in briquets and similar articles, so that they are rendered smokeless and odorless.

In the commercial manufacture of briquets wherein finely powdered coal or powdered coke, both of which are waste products, the latter being known commercially suitable binder such as coal tar, coal tar pitch, or oil tar, or oil tar pitch, and properly shaped to form briquets, it has been found in practice that the briquets give off a large quantity of smoke and the binder, in addition to giving off this objectionable volume of smoke, also has a disagreeable odor which materially reduces the sale of the briquets. By my invention I subject the briquets so formed to a continuous process whereby they are treated in my improved volatilizer, the gases or smoke given off in their treatment being utilized to carry on the process, rendering it continuous and extremely economical in that the briquets are fed forward by their own gravity, and, after the volatilizer has been properly heated and brought to the proper temperature, the further primary heat vof the volatilizer may be dispensed with, the entire process being then carried on by the gases given off by the briquets themselves,

. so that after the volatilizer is once started it requires very little attention and automatically treats the briquets and renders them smokeless and odorless.

In the accompanying drawings, in which one form of my improved volatilizer is shown, the same referencenumerals refer to similar parts in the several figures.

Figure 1 is a longitudinal vertical section substantially on the line 1--1 of Fig. 3; Fig. 2 is a transverse vertical section substantially on the line 2-2 of Fig. 1; Fig. 3 is a transverse fragmentary .view substantially on the line 33 of Fig. 1; and Fig. 4 is a longitudinal vertical section substantially on the line 44 of Fig. 3.

to be understood that a,

clined oven 1 or 2, as the case may be, or i any multiple of this number, as may be found convenient or expedient. These inclined ovens 1, 1 and 2, 2 are formed of fireclay and are arranged in the volatilizer 3, which is formed of fire-brick, so that their front ends 4, 4 will be higher than their rear ends 5, 5. The degree of inclination is such that the briquets (5, 6 are to be made to pass through the volatilizer 3 in a continuous stream by gravity. In practice I have found that excellent results are had when theovens 1 and 2 are arranged at substantially 37 degrees inclination, though this, of course, may be varied. The different gangs are substantially duplicates of each other and for the sake of brevity merely one gang will be described, it, of course, being understood that any multiple of such gangs may be used.

The fire brick inclined ovens 1, 1 are supported on the fire brick angular blocks 7 (Figs. 1, 2 and 3), some of which are mounted on transverse walls 40, 40 of the volatilizer 3 and others are mounted on other fire brick blocks 8 carried by the volatilizer. These blocks 7 are arranged at different elevations in the volatilizer 3 to correspond with the degree of inclination of thefire brick ovens 1 which rest upon them. As shown in Fig. 1 they are arranged at an elevation with relation to each other so as to give the fire-brick oven 1 substantially a 37 inclination.

Upon shelves 41, 41 formed on the interior of the volatilizer I mount fire brick tiles 11, 11. These tiles partly surround the ovens 1, 1 and support the upper vens' 2, 2. These tiles ll do not extend up to the roof 12 of the interior flue 14 of the volatilizer 3, Fig. 1. At intervals I mount bafile plates 13, 13 on the fire brick shelves 41, 41 extendin them,. up until they make contact with t e roof 12 of the interior flue 14 of the volatilizer 3. Two such bafile plates 13 are shown in Fig. 1, though, of course, it is eater or less number may be used as may e found convenient or expedient. In each one of these baflle permit a small portion of the products ofcombustion'to pass through the baflle plate, 5 but not a suflicient quantity to be objectionable. These sight holes 15 may be omitted, if desired.

At the front/16 of the volatilizer and beneath the upper ends 4, 4 of the different inclined ovens I mount a furnace 17' with grate bars 18, a'fuel door 119, and with primary air ports 20, 20. To dry out the volatilizer and to heatit up to the proper temperature so that it can start to volatilize automatically without any primary firing, I make a fire in the furnace 17 of coals, or some other fuel, and permit a certain amount of air to pass through the primary air ports 20, 20 u through the bed of coals so as to form 0. The products of combustion from this furnace 17, including the CO, pass through the flues 118, 118 and into the vertical flues 19, 42 passing'around and 'over lower ends 5, 5 and thence up to the roof 12 of the main passage 14 of the volatilizer, and along this roof until they meet the first baflle plat e 13', Fig. 1. They are then deflected downward through thepassages 21, 43 into the vertical passages 22, 44 back to the roof 12 of the main passage 14 along which they pass until they meet the second baflie plate 13 and are thence again deflected downward into the passages 23, 45 and caused then tov pass into the passages 24,

46 out through the stack 25, their passage being regulated by the damper 26 which controls the pressure of the gasesand products of combustion within the volatilizer 3, and the oven or ovens.

The briquets 6, 6 are dumped by hand or b any suitable machinery into the hopper 2;, some of them falling upon the shelf 28 and being deflected into the upper inclined ovens 2, 2, while theremaining port-ion of the briquets follow the lower-portion 29 of the hopper and are thence caused to pass through the inclined ovens 1, 1. As they dependent upon the inclination of the dif- 'ferent ovens, they are, in the beginning of the operation, subjected to the heat of the roducts of primary combustion from the urnace 17. In the upper part of each of the ovens 1, 1 and 2, 2 openings or ports.

circuitous path previously described, and

the briquets 6, 6 and thereafter proceed' the different ovens 1, 1 and 2, 2 near their pass down these inclined ovens 1, 1 and 2, 2 their flow being entirely due to gravity and P thence through the stack 25.. In addition to theprimary air ports 20,20 I form secondary' air ports 31, 31, Figs. 1 and 4, each secondary air port having preferably two openings. 32, 32 'in-the path of the products of primary combustion which follow their circuitous route over and around the inclined ovens 1, 1 and 2, 2. Through these secondary air ports 31, 31- the necessary lair is supplied from the exterior ofthe volatilizer 3 passing through the openings, or

ports 32, 32 to mix with the products of primary combustion from the furnace 17 and later with the ases driven off from the briquets 6, 6 WlllCh are being treated. The chemical action may be briefly stated to be that at first carbon monoxid CO is formed by combination of air with the fuel of thefire and later carbon dioxid CO by the combination of the CO With the air passing in through the secondary air ports. After the volatilizer has been started and .the process of treating the briquets has been initially begun-from theheat derived from the furnace 17, this furnace may be allowed to die down or go out, as it is not necessary for the further treatment of the briquets to be fed to the volatilizer, as the gases given off from them pass through thediferent ports-30, 30 and mix with the air from the secondary air ports 32, 32 and burn with an intense heat and themselves pass over and around and follow the circuitous path of the products of combustion previously described, and in this manner the waste gases driven off from the briquets is used to firethe volatilizer, and to complete the further treatment of the briquets which pass automatically down the different fire brick ovens 1, 1 and 2, 2 in a continuous stream. It is therefore clear that after the process is once started the briquets are.

treated automatically with their own waste gases and that all that is essential is to feed the briquets into the hopper 27 and remove the treated briquets at intervals, or continuously, as the case may be, from the boot or reservoir 33 arranged at the end of the inclined ovens 1, 1 and 2, 2. This boot 33 is of course gas tight and is provided with may be removed at intervals as desired. Preferably, however, some dlscharging, mechanism 1s provlded to continuously, or

intermittently, remove the treated briquetsfrom the boot or'reservoir 33. Such a discharging mechanism may be a screw. 47, the boot or reservoir, being provided with guides 48, 48 to guide the treated briquets into the path of the screw. This discharging mechanism whether it be a screw such as 47, orany other form of discharging mechanism, also serves to assist in regulating the passage of thegreen briquets through .the ovens, by removing the treated briquets 115 a door 34 through which the treated briquets withdrawn by the discharging mechanism serves to regulate the passage of the green briquets through the ovens and the time that they are treated.

On the upper part of the furnace 17 I preferably orm an arch 35. On this arch 35 I mount the support 9 which is provided with an aperture 36 so that the roducts of a combustion may. pass freely t rough the support 9 to equalize the pressure. I also preferably, though notnecessarily, provide the secondary air orts 31, 31 with any suitable form of va ves 49, 49 to regulate the supply of air passing through them.
